Referring now to the drawings, and particularly to FIGS. 1 to 4 thereof,there is illustrated a piece of furniture made in accordance with andembodying the principles of the present invention, a lefthand singlepedestal desk 100 having been shown for purposes of illustration. Thedesk 100 includes a desk top 101 at one end of which is disposed apedestal 150 supported by a pair of legs 500 having associated feet 520,the pedestal 150 having mounted therein a shelf 190, a box drawer 210and a file drawer 270, the shelf 190 being provided with a pull 1901,the box drawer 210 being provided with a pull 2101 and the file drawer270 being provided with a pull 270P. Mounted on the other end of thedesk top 101 is an end panel 450 supported by a pair of legs 550 havingassociated feet 570, the space between the pedestal 150 and the endpanel 450 at the rear of the desk top 101 being closed by a back panel400; as may be best seen in FIG. 3, the back panel 400 is provided witha pair of wiring openings 415 for the reception of telephone wires andthe like. There further is mounted on the desk top 101 a center drawer380 and a depending front wall or skirt 390, a lock 360 being providedin substantially the center of the front edge of the desk top 101 tolock the several drawers 210, 270 and 380.

The desk top 101 more specifically includes an edging 103 extendingaround the periphery thereof and formed of sheet metal and generallyextending downwardly and inwardly. The desk top 101 further carries adecorative trim 130 also extending around the periphery thereof. Thepedestal 150 has a rectangular rear wall 152 and a pair of substantiallyparallel side walls 153 extending forwardly therefrom and disposedsubstantially perpendicular thereto and parallel to each other, thecorners between the rear wall 152 and the side walls 153 being rounded.The forward edges of the side flanges 153 carry inwardly curved frontflanges 159 that extend substantially vertically and terminate inrearwardly directed flanges 159a. Disposed in the forward portion of thepedestal 150 is a front frame 160 formed of two substantially C-shapedchannels which in turn are essentially U-shaped in cross section, eachincluding a main wall 162 and a pair of integral side flanges 1-63extending normal thereto and parallel to each other. The free ends ofthe C-shaped channels disposed toward each other are joined by a splicechannel 164 placed in bridging relationship therewith. Finally, there isprovided on the side walls 153 internally of the pedestal 150 butdisposed-forwardly toward the front frame 160 a pair of drawer supports180 each including a main wall 182 and having on the verticallyextending edges thereof side walls that extend outwardly toward theassociated pedestal side wall 153.

As is illustrated in FIGS. 1 and 2, the pedestal 150 has mounted thereina shelf 190, a box drawer 210 and a file drawer 270. By reference toFIGS. 8, 9 and 11 to 13, the details of construction of the shelf 190and the mount ing thereof in the pedestal 150 will be described. Theshelf 190 includes a top 191 having a width slightly less than the widthof the interior of the pedestal 150 and a length slightly less than thelength of the pedestal 150 (see FIG. 9), the longitudinally extendingedges of the top 191 having depending side walls 192 disposedrespectively thereon and carrying on the lower edges thereof inwardlydirected support flanges 193 terminating in rounded and outturnedflanges 194 (see FIG. 11). The rear of the shelf 190 is provided with aback Wall 195 and formed on the rear of the side walls 192 are inturnedreinforcement flanges 196 disposed against the inner side of the backwall 195 and suitably secured thereto as by welding. The forward end ofthe top 191 carries a downwardly directed front wall 197 (see FIG. 9)that carries on the lower edge thereof a rearwardly directed L-shapedflange 198. The shelf 190 carries two pairs of bumpers 199, namely, arear pair of bumpers 199 each having a mounting stud 199a extendingthrough an opening in the rear flange 195 and a front pair of bumpers199 each having a mounting stud 199a extending through an opening in theL-shaped flange 198.

The shelf 190 is mounted upon two pairs of shelf glides 200 that aresubstantially identical in construction but are formed as mirror imagesof each other, the construction of one of the shelf glides 200 beingbest illustrated in FIGS. 11 to 13 of the drawings. Each shelf glide 200includes a body 201 that is essentially block shaped and has on theoutwardly disposed wall thereof a pair of longitudinally spaced apartpositioning studs 202 for assisting in mounting the shelf glide upon theassociated support structure; more specifically, the forward ones of theshelf glides 200 are mounted upon the front frame 160, the positioningstuds 202 extending through suitably disposed openings in the main wall162, and the rearward ones of the shelf glides 200 are mounted upon thedrawer supports 180, the positioning studs 202 extending throughsuitably disposed openings in the main walls 181. There further isprovided an opening 203 through each of the bodies 201 to receive a bolt204 extending therethrough and engaging an associated threaded openingin the associated main wall 162 or 181 as the case may be, therebyfirmly to mount the associated shelf glide 200 thereon. Each of theglide bodies 201 includes a lower surface 205 on which rests theassociated supporting flange 193 of the shelf 190, the support surface205 extending outwardly to the associated main wall 162 or 181, as thecase may be, and extending inwardly and terminating at an upstandingwall 206 integral with the body 201, the upper end of the Wall 206carrying a top flange 206a. The wall 206 includes an outwardly disposedsurface 207 and the flange 206a has an upper support surface 208thereon. When the shelf 190 is in the storage position thereofillustrated in FIG. 9, the major portion thereof is disposed rear wardlyor to the right with respect to the support and therefor rearwardly orto the right of the rearmost shelf glides 200, whereby the supportflange 193 engages the lower support surface 205 on the rear glides 200and serves as a fulcrum for pivoting the portion of the shelf in frontof or to the left of the support 180 upwardly, whereby the upper surfaceof the flange 194 engages the upper support surfaces 208 of the shelfglides 200 mounted on the front frame 160. Conversely, when the shelf190 is in the fully withdrawn or extended position, the support flanges193 rest upon the associated lower support surfaces 205 of the glides200 mounted on the front frame 160 and the flanges 194 abut against theupper support surfaces 208 on the shelf glides 200 mounted upon thesupports 180. It further is pointed out that when the shelf 190 is inthe full storage position illustrated in FIG. 9, the front bumpers 199abut against the shelf glides 200 mounted on the front frame 160, andwhen the shelf 190 is in the fully extended or withdrawn positionthereof, the rear bumpers 199 abut against and engage the shelf glides200 mounted on the supports 180.

It is an important feature of the present invention to form the shelfglides 200 of a lubric material, the preferred lubric material being asynthetic organic plastic resin, the preferred resin being an acetalresin such as that sold under the trademark Delrin. The bumpers 199 maylikewise be formed of such material, or may be formed of the usualelastomeric materials. In order to control the side movement of theshelf 190, a pair of buttons 209 is provided on the lefthand side asviewed in FIGS. 1, 2, 8 and 11, the buttons 209 being mounted upon theassociated main walls 162 and 181, respectively, and including mountingstuds 209a extending into suitable openings in the associated main wall.The buttons 289 are also preferably formed of the same lubric materialas the shelf glides 200 and are dimensioned so that the inner surfacethereof is disposed away from the surfaces 207 on the associated glides200 a distance just slightly greater than the lateral distance betweenthe outer surface of the shelf side wall 192 and the innermost point onthe rounded outturned flange 194. By this construction, accurate yeteasy control of the side motion of the shelf 190 is obtained duringmovement between the storage position thereof and the fully extendedposition thereof. The necessity of providing -a side rail on theinterior of the pedestal has also been eliminated, :all while providingsmooth and quiet mounting of the shelf 190 during all movement thereof.

The construction and mounting of the box drawer 210 is best illustratedin FIGS. 8, 9 and 14 to 20, inclusive. Referring first to FIGS. 8 and14, the box drawer 210 includes a bottom wall 211 that is substantiallyrectangular in shape and has a width slightly less than the interiorwidth of the pedestal 150 and has a length slightly less than the lengthof the pedestal 150 (see FIG. 9 also). Disposed on the longitudinallyextending side edges of the bottom wall 211 are upstanding inner sidewalls 212, the side walls 212 being disposed substantially parallel toeach other and normal to the bottom wall 211 and extending substantiallythe entire length thereof. Interconnecting the rear ends of the bottomwall 211 and the inner side walls 212 is a rear wall 213, all of thewalls n amed being mutually interconnected. Each of the side walls 212in addition includes an outer side wall generally designated by thenumeral 214, each of the outer side walls 214 including a bottom flange215, a lower support flange 216, a retaining flange 217, an upper support flange 218 and a connecting wall 219 disposed between the supportflanges 216 and 218. It will be understood that a single piece of sheetmetal is shaped to provide the various parts named, the bottom flange215 lying beneath the bottom wall 211 and being secured thereto as bywelding and the connecting wall 219 lying against the surface of theassociated wall 212 and being secured thereto as by welding. The twosupport flanges 216 and 218 are disposed parallel to each other andnormal to the drawer side wall and extend laterally outwardly withrespect thereto; and the retaining flange 217 extends upwardlysubstantially normal to the support flanges 216 and 218 and is spacedoutwardly a predetermined distance with respect to the connecting wall219, the support flanges 216 and 218 and the retaining flange 217extending substantially the entire length of the drawer 210. Extendingupwardly from the upper support flange 218 is a connecting section 222(see FIG. 8) on the upper end of which is an integral outstandingreinforcement section 223 and above which is another connecting sec tion224 carrying 'an upper outstanding reinforcement section 226 thatcarries on the inner portion thereof a downturned flange 227 disposedadjacent to an outwardly offset flange 228 on the upper edge of theassociated inner side wall 212. It will be understood that each of theportions and sections named is formed integral from the same piece ofsheet metal as that from which are formed the other portions of theouter side wall 214. In the construction, the connecting sections 222and 224 are disposed against the outer surface of the associated innerside wall 212 and are suitably secured thereto as by welding, whereasthe reinforcement sections 223 and 226 are spaced outwardly with respectto "the inner side wall 212. In passing it is noted that both sides ofthe box drawer 210 have the double wall construction described, and inthe interest of brevity, the construction of the other side of thedrawer 210 will not be described, but like reference numerals areapplied to like parts thereof.

The box drawer 210 is supported within the pedestal for movement betweena stonage position and an extended position on four glides disposed'between the support flanges 216 and 218 thereof. A first form of glide230 is provided on the lefthand side of the drawer 210 as viewed inFIGS. 1, 2, 8 and 14, this form of glide 230 including a generallyrectangular body 231 (see FIGS. 1'5 to 17 particularly). The glide body231 has formed integral therewith a mounting shank 232 disposed on theone side of the body 231 and having integral therewith a positioningstud 233 extending laterally therefrom and into an associated opening inthe main wall 162 or the main wall 181 of the from frame or the drawersupport as the case may be. There also is formed in the body 231 anopening 234 that connects with a like opening in the shank 232 toreceive therethrough .a bolt 235, the threaded shank of the bolt 235engaging in a complementarily threaded opening in the associated wall162 or 181, as the case may be, thereby in cooperation with thepositioning stud 233 firmly to mount the associated glide 230 upon thepedestal 150. The glide body 231 has an upper support surface 236 whichis substantially flat and .a lower support surface 237 which is alsosubstantially flat. Provided on the upper and lower outer sides of thebody 231 are outside guide walls 238, and provided on the upper andlower inner edges of the body 231 are inner side guide walls 239, theupper and lower guide walls 239 being separated by a recess 2390 in theinner surface of the body 231.

A second form of glide 240 is provided on the righthand side of thedrawer 210 as viewed in FIGS. 1, 2, 8 .and 14, this form of glide 240including a generally rectangular body 241 (see FIGS. 18 to 20particularly). The glide body 241 has formed integral therewith amounting shank 242 disposed on one side of the body 241 and havingintegral therewith a positioning stud 243 extending laterally therefromand into an associated opening in the main wall 162 or the main wall 181of the front frame 160 or the drawer support 180, as the case may be.There also is formed in the body 241 an opening 244 that connects with alike opening in the shank 242 to receive there-through a bolt 245, thethreaded shank of the bolt 245 engaging in 'a complementarily threadedopening in the associated wall 162 or 181, as the case may be, therebyin cooperation with the positioning stud 243 firmly to mount theassociated glide 240 upon the pedestal 150. The glide body 241 has anopen support surface 246 which is substantially flat and a lower supportsurface 247 which is also substantially flat.

Referring to FIG. 9, it will be seen that the box drawer 210 in thestorage position illustrated therein has the major portion thereofdisposed rearwardly or to the right with respect to the drawer supports180, whereby the portion of the drawer to the right of the drawersupports 180 is supported in cantilever fashion. As a result, the uppersupport flanges 218 rest upon and are supported by the upper surfaces236 and 246, respectively, of the glides 230 and 240 mounted upon thedrawer supports 180, but the lower support flanges 216 engage the lowersupport surfaces 237 and 247, respectively, on the glides 230 and 240mounted upon the front frame 160. However, when the drawer 210 is movedto the fully extended position thereof, i.e., to the left as viewed inFIG. 9, the major portion thereof is supported in cantilever fashionoutside of the pedestal 150, whereby the upper support flanges 218thereof rest upon the upper surfaces 236 and 246, respectively, of theglides 230 and 240 mounted on the front frame 160, while the lowersupport flanges 216 thereon rest against the lower support surfaces 237and 247, respectively, of the glides 230 and 240 mounted on the drawersupports 180. Side movement of the drawer 210 during movement betweenthe storage and extended positions thereof is controlled by thecooperation between the retaining flange 217 and the outside guide wall238 and between the connecting wall 219 and the inside guide walls 239,it being noted that the entire side guide function is performed by theglides 230, the glides 240 contributing not at all to the side guidefunction is performed by the glides 230, the glides 240 contributing notat all to the side guide function. Preferably both the glides 230 andthe glides 240 are formed of a lubric material, the preferred materialbeing a synthetic organic plastic resin, the preferred resin being anacetal resin such as that sold under the trademark Delrin, wherebysmooth and quiet operation is obtained when moving the box drawer 210between the storage and extended positions thereof.

The construction of the drawer head for the box drawer 210 is bestillustrated in FIGS. 26 to 29, inclusive, wherein it will be seen thatthere is provided an outer front wall 250 that is generally rectangularin shape and extends outwardly beyond the side walls 212 and upwardlybeyond the upper edges of the side walls 212 and downwardly as at 251below the bottom wall 211. Disposed on the side edges of the front wall250 are side flanges 259 (see FIG. 6) that extend rearwardly and carryon the rear edges thereof inturned flanges 259a. Disposed on the loweredge of the front wall 250 is a rearwardly directed flange 252underlying and spaced from the undersurface of the bottom wall 211, therear edge of the flange 252 carrying an upturned flange 253 extendingupwardly to the undersurface of the bottom wall 211 and carrying thereona rearwardly directed attachment flange 254 lying against theundersurface of the wall 211, means being provided suitably to secure asby welding the outer front wall 250 to the bottom wall 211 and the sidewalls 212. The upper end of the front wall 250 carries a U-shapedretaining flange 255 including a rearwardly and slightly downwardlydirected portion 256 and a downwardly directed portion 257 disposedsubstantially parallel to and spaced from the front wall 250. Spacedfrom the lower end of the front wall 250 and struck from the bottom wall211 are two upwardly extending projections 258.

Disposed behind the outer front wall 250 and within the drawer 210 is aninner front wall 260 that extends substantially between the side walls212 and from the bottom wall 211 upwardly to the U-shaped retainingflange 255 on the front wall 250. The inner front wall 260 comprises apair of reinforcing ribs 261 each including a forward portion 262 and apair of connecting portions 263. At the upper end of the inner frontwall 260 is a forwardly offset flange 264 that lies against the innersurface of the downwardly directed portion 257 and carrying on the upperend thereof a top Z flange 265 extending forwardly to the inner surfaceof the outer front wall 250 and in turn carrying a front flange 266lying against the inner surface of the outer front wall 250. In theassembled condition illustrated in FIGS. 26 and 28, the lower end of theinner front wall 260 extends downwardly to the bottom wall 211 and isdisposed forwardly with respect to the projections 258 and carries onthe lower end thereof a forwardly directed bottom Z flange 267 thatextends forwardly to the inner surface of the outer front wall 250 andin turn carries thereon a downwardly extending front flange 268 thatlies against the inner surface of the outer front wall 250. Finally,bodies of mastic 269 are provided between the U-shaped retaining flange255 and the upper end of the inner front wall 260, between the ribs 261and the front wall 250 and between the Z flange 267 and the outer frontwall 259, further to interconnect the front walls 250-260 and to providea sound deadening effect therebetween. The bodies of mastic 269 arepreferably formed of a heat curing mastic sold under the trademarkPresstite No. 719.

The assembly of the inner front wall 260 with respect to the outer frontwall 250 is diagrammatically illustrated in FIG. 27. Prior to assemblyof the parts, the bodies of 8 mastic 269 are respectively placed uponthe upper portion of the inner front wall 260, upon the ribs 261 and theZ flange 267, after which the upper end of the inner front wall 260 ispushed into the U-shaped retaining flange 255 as is diagrammaticallyillustrated in FIG. 27. The proportions among the parts is such that theupper end of the inner front wall 260 may be moved upwardly into theU-shaped retaining flange 255 a distance greater than the verticalextent thereof thereinto in the fully assembled position, whereby incombination with the springlike character of the inner front wall 260imparted thereto by the material of construction, namely, sheet metal,and the provision of the ribs 261, permits the lower end of the innerfront wall 260 to pass above the projections 258. Having passed theprojections 258 and with the front flange 268 against the inner surfaceof the outer front wall 250, the entire inner front wall 260 can then bemoved downwardly to seat the lower end thereof between the outer frontwall 250 and the projections 258 as is diagrammatically illustrated inFIG. 28. Gravity and the bodies of mastic 269 serve to hold the parts inthis position.

Disposed lowermost in the pedestal is the file drawer 270, the detailsof construction and the mounting thereof being best seen in the FIGS. 8,l0 and 21 to 25 of the drawings. Referring first to FIG. 8, the filedrawer 270 includes a bottom wall 271 that is generally rectangular inshape and has a width slightly less than the inner width of the pedestal150 and a length slightly less than the length of the pedestal 150 (seeFIG. 10 also), the longitudinally extending edges of the bottom wall 271carrying inner side walls 272 integral therewith and extending upwardlytherefrom substantiall normal thereto and substantially parallel to eachother. Joining the rear edges of the side walls 272 and the bottom wall271 is a rear wall 273. The side walls of the drawer 270 are of doublewall construction and accordingly there is provided on each of the innerside walls 272 an outer side wall 274, the outer side walls 274 beingidentical in construction whereby only one will be described in detail,each outer side wall 274 being formed of a single piece of sheet metalbent to provide the several parts thereof. More particularly, the outerside wall 274 includes a bottom flange 275 (see FIG. 21) that liesbeneath the underside of the bottom wall 271 and extends outwardlybeyond the adjacent inner side wall 272 and upwardly to provide a lowersupport flange 276, the material being folded to provide a doublethickness at this point; integral with the lower support flange 276 is aretaining flange 277 and also integral with the support flange 276 is anupstanding connecting wall 279 that connects with an upper supportflange 278 also of double thickness construction and being formedintegral with a connecting section 282 (see FIG. 8 also); the upper endof the connecting section 282 is integral with an outstandingreinforcement section 283 that in turn is integral with the attachmentsection 284. As illustrated, the bottom flange 275 lies against theundersurface of the bottom wall 271 and is suitably secured thereto as bWelding, while the connecting wall 279, the connection section 282, andthe attachment section 284 are all disposed against the outer surface ofthe associated inner side wall 272 and are likewise suitably securedthereto as by weldng. By contrast, the reinforcement section 283 isspaced outwardly with respect to the adjacent inner side wall 272. Theupper edge of each of the inner side walls 272 carries outwardlydirected holding flanges 286 which in turn carry on the outer edgethereof an upwardly directed and upstanding flange 287 which in turncarries on the upper edge thereof an inwardly directed top flange 288carrying on the inner edge thereof a depending retaining flange 289, allas will be described more fully hereinafter.

The file drawer 270 is supported within the pedestal 150 on a pair oflefthand rollers 290 (as viewed in FIGS 1, 2, 8 and 21), a pair ofrighthand rollers 290A and a pair of lefthand guides 300. Each of therollers 290 includes an inner race 291 (see FIG. 10), a mounting shank292 and a plurality of ball bearings 2'93 disposed on the inner race 291and held thereon by an outer race contained in a support member 294, thesupport member 294 having a support surface 295 around the outerperiphery thereof, the support surface 295 being essentially cylindricalin shape and engageable with the support flanges 276 and 278 on theassociated drawer. A bolt 296 passes through the roller 290 and throughthe shank 292 thereof and engages a threaded opening in the associatedmain wall 162 or 181, respectively, of the associated front frame 160 ordrawer support 180, as the case may be. Associated with each of thelefthand rollers 290 is a guide 300, each of the guides 300 including asubstantially rectangular body 301 having formed integral therewith andextending from one edge thereof a positioning stud 302 extending througha suitable opening in the associated main wall 162 or 181, as the casemay be. The other end of the body 301 has an opening 303 therein forreceiving therethrough the bolt 296 for mounting both the roller 290 andthe guide 300 upon the associated main wall 162 or 181, as the case maybe. Adjacent to the opening 303 but spaced a short distance therefromand concentric therewith is a first arcuate recess 305 for receiving theshank 292 of the associated roller 290 therein, and also disposedconcentric therewith and spaced farther out therefrom is an arcuatesecond recess 307 for receiving the support member 294 therein. Disposedabove and below the body 301 are upper and lower wings 306 that extendlaterally inwardl beyond the inner surface of the support member 294 andhaving inwardly facing inside guide walls 311 thereon and outwardlydisposed outside guide walls 310 thereon. The distance between the guidewalls 310 and 311 is slightly less than the distance between the innersurface of the retaining flange 277 and the adjacent outer surface ofthe connecting wall 279, whereby the guide 300 provides control of sidemovement of the file drawer 270 during the movement thereof between thestorage position illustrated in FIG. 10 and an extended position whereinthe major portion of the drawer 270 is disposed outside of the pedestal150. Finally, the righthand rollers 290A are provided (see FIGS. 21 and25) and each includes an inner race 291A, a mounting shank 292A and aplurality of ball bearings 293A disposed upon the inner race 291A andheld thereon by an outer race on a support member 294A, the supportmember 294A having a support surface 295A about the periphery thereofthat is substantially cylindrical. A bolt 296A passes through an openingin the inner race 291A and serves to mount the roller 290A upon theassociated main wall 162 or 181, as the case may be. In passing it isnoted that the width of the support surface 295 and the support surface295A both are substantially less than the distance between the innersurface of the associated retaining flange 277 and the outer surface ofthe associated connecting wall 279, whereby control of the side movementof the drawer 270 is controlled only by the action of the guides 300.

Preferably the guides 300 are formed of a lubric material, the preferredlubric material being a synthetic organic resin, preferably an acetalresin such as that sold under the trademark Delrin. Likewise, it furtheris pointed out that when the file drawer 270 is in the storage positiontherefor illustrated by the dashed lines in FIG. 10, the major portionof the file drawer 270 is disposed inwardly or to the right of thedrawer supports 180, whereby the major portion of the drawer 270 ismounted in cantilever fashion within the pedestal 150. As a consequence,the upper support flanges 278 contact the surfaces of the rollers 290and 290A mounted on the drawer supports 180, whereas the lower supportflanges 276 contact the rollers 290 and 290A that are mounted on thefront frame 160. On the other hand when the file drawer 270 is in thefully extended position thereof, the major portion of the file drawer270 is disposed outwardly or to the left of the front frame 160, wherebythe major portion of the drawer 270 is mounted in cantilever fashionoutside of the pedestal 150. As a consequence, the upper support flanges278 contact the surface of the rollers 290 and 290A mounted on the frontframe 160, whereas the lower support flanges 276 contact the rollers 290and 290A that are mounted on the drawer supports 180.

Further details of construction of the file drawer 270, and particularlyof the construction of the drawer head therefor, are illustrated in FIG.30 of the drawings. As will be best seen therein, the top flanges 288and the retaining flanges 289 are cut away at the forward or lefthandend of the drawer 270 and there are provided thereon front side flanges315 extending upwardly from the inner side walls 272. The rear wall 273further has formed therein an inturned U-shaped flange 316 on the upperedge thereof and extending substantially between the retaining flanges289. Mounted on the forward end of the drawer 270 and extending beyondthe side walls 272 and upwardly thereabove and downwardly therebelow isan essentially rectangular outer front wall 320, the lower end of thewall 320 extending below the bottom wall 271 as at 321 and having on thelower edge thereof a rearwardly directed fiange 322 carrying on the rearedge thereof an upturned flange 323 extending upwardly to the undersideof the bottom wall 271 and carrying a rearwardly directed attachmentflange 324 thereon. The upper end of the outer front wall 320 carries aU-shaped retaining flange 325 including a rearwardly and slightlydownwardly directed portion 326 and a downwardly directed portion orflange 327, the flange 327 being disposed substantially parallel to theouter front wall 320. The bottom wall 271 has a pair of upwardlyextending projections 328 struck therefrom. The outer front wall 320 issecured to the forward end of the drawer 270 such as by welding at theattachment flange 324 and at the forward edges of the side walls 272.Disposed within the drawer 270 but against the outer front wall 320 isan inner front wall 330, the wall 330 including a pair of laterallyextending reinforcing ribs 331 having forward portions 332 andconnecting portions 333, the ribs 331 extending the entire width of theinner front wall 330. The upper end of the wall 330 carries a forwardlyoffset flange 334 disposed in front of the downwardly directed flange327 of the Z-shaped retaining flange 335, the flange 334 in turncarrying on the upper edge thereof a forwardly directed top flange 335that in turn carries on the forward edge thereof an upturned frontflange 336 disposed against the inner surface of the outer front wall320. The bottom end of the inner front wall 330 carries a bottom flange337 that is forwardly and upwardly directed and carries on the forwardedge thereof a downturned front flange 338 disposed against the innersurface of the outer front wall 320. It will be seen that theconstruction of the drawer head including the outer front wall 320 andthe inner front wall 330 of the drawer 270 is substantially like that ofthe drawer 210, and in the interest of brevity the manner of assemblywill not here be repeated, it merely being pointed out that bodies ofmastic 339 are disposed between the wall 320 and the parts 331, 328 and336 and insure that the upper end of the inner front wall 330 isretained within the U-shaped retaining flange 325 and together with theprojections 328 insure that the lower end of the inner front wall 330 isheld in position immedi ately adjacent to the outer front wall 320.

There further is provided within the file drawer 270 a compressor plate340' (see FIGS. 30 to 34, inclusive), the compressor plate 340 servingto hold the material stored within the file drawer 270 in the forwardportion thereof and against the drawer head in the usual manner. Thecompressor plate 340 includes a main body 341 which is generallyrectangular in shape (see FIG. 32) having square lower corners andhaving formed intermediate the height thereof a rearwardly disposedreinforcing rib 349 and having formed toward the upper end a rearwardlydirected flange 342 carrying an upstanding flange 343 which in turncarries a forwardly directed flange 344 to which is integrally connectedan upper body 345, the upper body 345 having a U-shaped curved andrearwardly extending handgrasp portion 346 on the upper end thereofincluding an inturned flange 347 disposed therebeneath for reinforcementpurposes. There further are provided in the flange 343 a pair ofopenings 348 by means of which a pair of guide brackets 350 are attachedto the compressor plate 340, the righthand opening 348 being elongatedto permit adjustment. The guide brackets 350 are substantially identicalin construction, one being the mirror image of the other. Asillustrated, each of the guide brackets350 includes an attachment flange351 which extends laterally of the drawer 270 and fits between theflanges 342 and 344 of the compressor plate 340 and against the flange343 thereof, the guide brackets 350 having circular openings 352 thereinto receive screws 353 therethrough for attachment of the guide bracket350 to the compressor plate 340, the elongated righthand opening 348permitting adjustment of the righthand guide bracket 350 with respect tothe compressor plate 340 thereby to accommodate minor variations in thewidth of the drawer 27 0. In passing it is noted that as illustrated inFIGS. 30 and 34, the forward surfaces of the attachment flanges 351 arein substantial alignment with the forward surfaces of the main body 341and the upper body 345 of the compressor plate 340. Integral with eachof the attachment flanges 351 is a forwardly directed arm 355. The arms355 are adapted to lie upon the holding flanges 286 disposed on theupper edges of the drawer 272 and to extend upwardly into the spacebetween the upstanding flange 287 and the inner flange 289, whereby thearms 355 are restrained in the vertical movement by the holding flange286 and the top flange 288. As may be best seen in FIG. 34, each of theholding flanges 286 has a series of openings 312 therein, the openings312 being rectangular in shape with the longer dimension thereof,disposed longitudinally of the drawer 270. The lower surface of each ofthe arms 355 carries a downwardly and rearwardly directed rear finger387 thereon adapted to fit in one of the openings 312 (see FIG. 31) anda downwardly and rearwardly directed front finger 388 thereon adapted tofit in the adjacent forward opening 312. The upper surface 358 of eachof the arms 355 slopes downwardly to the rear as is best illustrated inFIG. 30 from a point immediately below the top flange 288 at the forwardportion thereof and downwardly to a point spaced just slightly above theflange 344 on the compressor plate 340 adjacent to the rear end thereof,whereby the arms 355 and the associated fingers 387 388 can be movedfrom the engaging or down position illustrated by solid lines in FIG. 30and by the dashed lines in FIG. 31 to a disengaged or up positionillustrated by solid lines in FIG. 31, the arms pivoting about the lowerfront end 359 thereof in a manner such as to clear the fingers 387 and388 from the associated openlngs 312, thereby to permit longitudinaladjustment of the compressor plate 340 along the file drawer 270. It ispo1nted out that such upwardly pivoting and longitudinal movement of thecompressor plate 340 can be achieved by the user grabbing the handgraspportion 346 at the upper end of the compressor plate 340, whereby tomove the parts to the solid line positions illustrated in FIG. 31. Whenthe compressor plate 350 is in the substantially desired longitudinallyadjusted position thereof, the user needs simply to release thehandgrasp portion 346 whereupon gravity will tend to return thecompressor plate 340 tothe lower position thereof and dispose thefingers 387 and 388 upon the holding flange 286. If the lower ends ofthe fingers 387 and 388 are in vertical alignment with a pair ofadjacent openings 312, then the fingers 387 and 388 will fall thereinto,thereby fixedly to position the compressor plate 340 in the adjustedposition with respect to the drawer 270. On the other hand, if thefingers 387 and 383 are not positioned vertically above an adjacent pairof the openings 312, then they will fall upon the upper surface of theholding flange 286, and will be moved rearwardly therealong due to thepressure of the material contained between the drawer'head at the frontend of the drawer 270 and the compressor plate 340, and as soon as thefingers 387-388 are moved over a pair of the openings 312, the fingers387-388 will fall thereinto under the urging of gravity, therebyautomatically to position the compressor plate 340 within the drawer270.

' Mechanism is provided for locking the drawers 210 and 270 Within thepedestal 150 in the storage positions thereof, and also to lock thecenter drawer 380 in the storage position thereof Within the desk top101. To this end a lock 360 has been provided in the front edging 103 ofthe desk top 101, the lock 360 being disposed generally centrally of thedesk top 101 and over the center drawer 380 therein. The usual keyopening is provided whereby upon insertion of the proper key, the partscan be turned between the locked position thereof and the unlockedposition thereof. In the operation of the lock 360 by means of a key aflexible wire cable 364 is moved,

the cable extending along a latch channel 370. The latch channel 370includes a main wall 371 suitably secured to the adjacent pedestal sidewall 153 as by welding and having extending forwardly therefrom a pairof side walls 372 from which extend laterally outwardly a pair of firstretaining flanges 373 from the outer edges of which extend inwardlydirected support flanges 374 on the inner edges of which are a pair ofinturned second retaining flanges 375. At the upper end of the latchchannel 370, the second retaining flanges 375 are provided with cutouts376 therein for insertion of latches as will be described more fullyhereinafter. The latch channel cable guide 367 is fixedly secured in theupper end of the latch channel 370 and has a curved bearing surface 369that directs the cable 364 through a 90 angle turn so as to direct thecable downwardly and along the length of the latch channel 37 0.

Referring to FIG. 8, it will be seen that disposed within the latchchannel 370 is a pair of latches 385, a latch 385 being provided for thebox drawer 210 and a latch 385 being provided for the file drawer 270.All of the latches 385 are of identical construction, whereby only onewill be described in detail with special reference to FIGS. 5 to 10,inclusive. Each of the latches 385 is more particularly mounted upon anassociated latch block 386 that is shaped and formed to move verticallywithin the latch channel 370 between the two sets of retaining flanges373 and 375, the associated latch 385 extending outwardly into thepedestal body and being formed integral with the latch block 386 (seeFIG. 6 particularly). A vertical opening is provided in the rear of thelatch block386 to receive the cable 364 therethrough and the block 386is staked as at 377 to connect the latch block 386 to the cable 364. Thelatch 385 includes an abutment surface 387 which engagesa keeper on theassociated drawer to provide the locking action, and'also has thereon acam surface 388 which is useful in permitting an open drawer to be movedto the storage position while the locking mechanism is in the lockedposition thereof and without the necessity of moving the parts to theunlocked position thereof. Finally, the lower latch block 386 is engagedby a spring 389 (see FIG. 10) having the upper end thereof connected tothe latch block 386 and having the lower end thereof fixedly connectedto the lower end of the latch channel 370. i

In order to complete the locking mechanism, each of the drawers in thepedestal is provided with a keeper on the outer side wall thereof.Referring to FIGS. 5 to 8 of the drawings, it will be seen that a keeper220 including an attachment flange 221 has been provided on the outerside wall 214 and particularly on the connecting section 222 thereof andsecured thereto as by welding, the keeper 220 extending laterallyoutwardly substantially normal to the associated drawer side wall. Whenthe latch 385 is in the upper or latching position thereof, the abutmentsurface 387 thereof is in horizontal alignment with and immediatelydisposed in front of the keeper 220, whereby the drawer 210 is locked inthe storage position thereof. However, when the latch 385 is moved tothe release position thereof, it is out of alignment with the keeper220, whereby the drawer 210 may be moved between the storage andextended positions thereof. The necessary movement of the latch 385between the latching and release positions thereof is obtained by theoperation of the lock 360 to move the parts from the locked positionillustrated to the unlocked position. The file drawer 270 likewise isprovided with a keeper 280 (see FIG. 8) which engages an associatedlatch 385 in the same manner as the latch 385 engages the keeper 220 onthe box drawer 210.

The latches 385 also serve as an outer stop to limit the distance thatthe drawers 210 and 270 can be withdrawn from the pedestal 150 withoutcomplete removal thereof. Referring particularly to FIGS. and 7, of thedrawings, it will be seen that there has been provided on each of thedrawers 210 and 27 0 a stop arm or bracket 225 that is essentiallyU-shaped and is attached to the outer side wall of the associated drawerand in horizontal alignment with the latch 385 when it is disposed inthe release position thereof, i.e., the lowermost position thereof asillustrated in FIG. 7. Mounted in the stop bracket 225 is a rubberbumper 229, and accordingly, upon withdrawl of the drawer, such as thedrawer 210, from the pedestal 150, the bumper 229 abuts against theabutment surface 387 on the latch 385, thereby to limit the withdrawalof the drawers from the pedestal 150. However, should it be desiredcompletely to remove a drawer from the pedestal 150, the lockingmechanism need only be moved to the locking position after partialwithdrawal of the drawer that it is desired to remove, such movement ofthe parts to be looking position shifting the latch 385 to the upper orlocked position so that the stop bracket 225 and the bumper 229 carriedthereby now clear the latch 385, whereby the drawer 210 can becompletely removed from the pedestal 150.

Due to the fact that the latches 385 are continually urged toward alower position thereof by means of the spring 389, each of the latches385 can be momentarily shifted upwardly by the application of suitableforce to the cam surfaces 388 thereof. For example, if a drawer 210 or270 is in the partially open or extended position thereof, andthereafter the locking mechanism is placed in the locked positionthereof so as to move the latches 385 to the upper or locked positionthereof, the latch 385 will be in longitudinal alignment with the keeper220 or 280, as the case may be; however, the keepers have the upper edgethereof disposed slightly below the upper edge of the latch 385 when itis in the latching position thereof, whereby the upper edge of a keeperengages the cam surface 388, thereby to move the latch 385 and theassociated parts upwardly against the action of the spring 389 until thekeeper passes behind the abutment surface 387 on the latch 385, afterwhich the spring 389 automatically returns the latch 385 to the latchingposition to engage in front of the keeper and prevent subsequentwithdrawal of the drawer until the latch 385 is moved to the lower orrelease position thereof.

Fundamentally the desk 100 is formed of sheet metal with the exceptionof the several parts mentioned during the above description.Furthermore, the sheet metal forming the various parts is of relativelylight gauge, as will be appreciated from the following example of thegauge of the sheet metal utilized to form various parts of the desk 100.In a typical construction of the box drawer 210 and the file drawer 270,the bottom side and rear walls thereof are formed of 24 gauge steel, theouter front walls thereof are formed of 22 gauge steel, the inner frontwalls are formed of 26 gauge steel.

The other parts of the desk not described in detail hereinabove arefully illustrated and described in the above-mentioned copendingapplication Ser. No. 503,517, new Patent No. 3,368,955, and accordinglyreference is made thereto and the disclosure thereof incorporated hereinin its entirety.

From the above description it will be seen that drawers of improvedconstruction have been provided having side walls formed of double wallsshaped to provide support flanges and retaining flanges and having adouble wall head of novel construction and connection, a body of masticbeing provided to interconnect the inner and outer walls of the drawerhead to provide an improved connection therebetween. Finally, there hasbeen provided in the drawer an improved compressor plate constructionincluding in the improved compressor brackets molded of lubric materialand constructed and arranged to provide for self-locking upon releasethereof .due to the downward force of gravity and a rearward forceresulting from the pressure of material lying between the front of thedrawer and the compressor.
